Products classified under Tariff item 3920.79
Cellophane Candy Wrapper Sheets
Pre-printed 0.03 mm cellophane sheets for individual hard candy wrappers. Cellophane is regenerated cellulose, a cellulose derivative, and the printing is subsidiary to the primary packaging use. These are thin noncellular films, not reinforced or combined with other materials.
3920.79.00Cellophane Conservation Archival Film
Acid-free 0.04 mm cellophane for document conservation interleaving sheets. Cellophane is regenerated cellulose, a cellulose derivative, and the film is noncellular and unsupported. These sheets are used to protect documents without chemical interaction.
3920.79.00Cellophane Packaging Film
Thin, transparent cellophane film made from regenerated cellulose, typically 0.02-0.05 mm thick, used for wrapping food products like candies and cigarettes. It falls under this tariff item as a noncellular film of a cellulose derivative, not reinforced or combined with other materials.
3920.79.00Cellophane Tape Backing Film
Clear 0.035 mm regenerated cellulose film serving as backing for transparent adhesive tapes. This is a noncellular, unreinforced sheet of a cellulose derivative, not exceeding 0.076 mm in thickness. The film is not combined with adhesive, which would change classification.
3920.79.00Cellulose Acetate Capacitor Dielectric Film
High-purity 0.01 mm cellulose acetate film for use as dielectric layers in electronic capacitors. Cellulose acetate is a cellulose derivative, and the film is noncellular, unreinforced, and not exceeding 0.076 mm in thickness. The purity meets the 95% polymer content rule for classification.
3920.79.00Vulcanized Fiber Abrasive Backing Sheets
Non-reinforced vulcanized fiber sheets used as backing for bonded abrasives and sanding discs. Vulcanized fiber is a cellulose derivative processed with zinc chloride, giving it exceptional tear strength for high-speed applications. These sheets are in primary plate/sheet form and are not reinforced or combined with other materials.
3920.79.00Vulcanized Fiber Arc Chute Sheets
Non-reinforced sheets of vulcanized fiber cut for circuit breaker arc chutes to extinguish electrical arcs. The material's heat resistance and non-conductivity make it suitable without chemical modification beyond vulcanization. These are plates/sheets of a cellulose derivative in primary form.
3920.79.00Vulcanized Fiber Battery End Plates
Rigid noncellular plates of vulcanized fiber used as end insulators in lead-acid batteries. The material's mechanical strength and acid resistance suit it for this application without reinforcement. These are plates of a cellulose derivative, not further worked beyond cutting into rectangles.
3920.79.00Vulcanized Fiber Electrical Insulation Sheets
Noncellular plates and sheets made from vulcanized fiber, a cellulose derivative processed with zinc chloride for high density and strength. These are used primarily for electrical insulation in motors and transformers. The sheets are not reinforced or combined with other materials, falling under this tariff item.
3920.79.00Vulcanized Fiber Gaskets and Washers
Thin noncellular sheets and strips of vulcanized fiber cut into gasket and washer forms for mechanical seals. Vulcanized fiber's oil and water resistance makes it ideal for automotive and machinery applications. These are plates/sheets of a cellulose derivative, not reinforced or combined.
3920.79.00Vulcanized Fiber Knife Handle Blanks
Noncellular sheets and blocks of vulcanized fiber rough-cut for custom knife handles. Moisture resistance and machinability without support classify it here. These are plates/sheets of a cellulose derivative, not further worked beyond cutting into rectangles.
3920.79.00Vulcanized Fiber Nameplate Blanks
Flat noncellular foil and strip of vulcanized fiber for engraving into machinery nameplates. Durable for outdoor exposure without reinforcement. These are plates/sheets of a cellulose derivative, not further worked.
3920.79.00Vulcanized Fiber Shim Stock Sheets
Thin precision sheets of noncellular vulcanized fiber used for shimming in machinery alignment. High tensile strength and machinability without lamination qualify it under this subheading. These are plates/sheets of a cellulose derivative, not further worked.
3920.79.00Vulcanized Fiber Slot Liners
Thin strips and foil of noncellular vulcanized fiber for lining motor stator slots. Provides phase insulation without reinforcement. These are plates/sheets of a cellulose derivative, not further worked beyond cutting into strips.
3920.79.00Vulcanized Fiber Transformer Pressboard
Dense noncellular plates of vulcanized fiber serving as pressboard in oil-immersed transformers. High compressive strength without lamination fits this cellulose derivative subheading. These are plates of a cellulose derivative, not further worked.
